DNB 96/97 jazzy tune

Bought this tune as a promo press in 96/97 in London.
Somebody stole it back in the days, so i forgot the artist.
It has a beautiful female vocal hook, that goes “you keep me up every night, you keep me up, keep me up, ... , now i found ... (or something like that)”.
Has anyone got a clue, which tune is it?
Would really like to hear it again ...
